- OBJECTIVES. The authors studied complications of transpedicular stabilization methods. SUMMARY OF BACKGROUND DATA. One hundred and sixty-three consecutive transpedicular stabilization procedures were performed between January 1987 and December 1991. The indications for stabilization were trauma (33 cases), metastatic spinal disorder (30 cases), spinal stenosis (33 cases), spondylolisthesis (27 cases), ankylosing spondylitis (6 cases), low back pain (22 cases), and miscellaneous (12 cases). METHODS. Patients records and the entire series of radiographs for each case were scrutinized by independent observers. All per- and postoperative complications, including implant loosening and fatigue, were recorded. Clinical and radiographic survivorship analyses of the implants were performed. RESULTS. Early complications were unusual and none were associated with permanent morbidity. The probability of not having the implant removed in the first postoperative year was 85%. There was a 40% risk of radiographic failure, defined as loosening or implant fatigue, at 6 months. The outcome was more favorable in cases in which anterior vertebral interbody fusion was also performed. CONCLUSIONS. Transpedicular fixation is a safe procedure with a low incidence of serious per- and early postoperative complications. The mechanical durability of transpedicular fixators used alone is a cause for concern.

- 40 patients with transversal or short oblique fractures of the proximal shaft of the fifth metatarsal bone (Jones fracture) were treated with full weight bearing with or without elastic bandage in 39 cases and plaster cast immobilization in one. 24 cases were acute traumatic fractures, 14 stress fractures and 2 refractures. After 17 (11-26) years, 33 of the fractures had healed primarily, evidence of refracture or delayed union was found in 7 and there were no non-unions. All but one of the patients were free of symptoms.

- Fifty-six patients who had had a fracture of the scaphoid from January 1950 through December 1959 were interviewed, re-examined, and had radiographs made of both hands an average of thirty-six years (range, thirty-one to forty years) later. The average age at the time of the treatment was twenty-eight years (range, fifteen to forty-five years). Fifty-two of the fifty-six patients were treated at the time of the fracture; the other four had a non-union when first seen. The rate of non-union for the fresh fractures at the most recent follow-up examination was 10 per cent (five of fifty-two). Dorsal intercalated-segment instability was found in three of the fifty-six patients; all three had a pseudarthrosis and manifest radiocarpal osteoarthrosis. Marked radiocarpal osteoarthrosis developed in only one (2 per cent) of the forty-seven patients who had a healed fracture; it was far more common in the group that had a pseudarthrosis, in which the prevalence was five of nine patients. Manifest osteoarthrosis also seemed to be associated with pain or weakness: it had developed in only three (6 per cent) of the forty-nine patients who did not have any symptoms at the re-examination, compared with three of the seven who had symptoms.

Jones fracture. Surgical versus nonsurgical treatment
- 1994

Tidskriftsartikel (refereegranskat)abstract
- Sixty-three patients with 66 transverse and short oblique fractures of the proximal shaft of the fifth metatarsal bone (Jones fracture) were evaluated an average of five years (range, one to ten years) after the injury. There were 27 acute fractures and 39 chronic, or stress, fractures. The primary treatment was surgical for one third of the injuries and nonsurgical for the others. Surgical treatment consisted of the insertion of medullary screws. Nonsurgical treatment consisted of the application of either a plaster cast or an elastic bandage. Almost one fourth of the fractures treated nonsurgically later had to be treated surgically because of delayed unions or refractures. Late surgery was required in 12% of acute fractures and in 50% of chronic fractures with sclerosis narrowing the medullary canal. Irrespective of the primary treatment, all the patients had full function at the time of the follow-up evaluation, and no nonunions were diagnosed.
